From 1967, M.A.B. was run by Thomas A. Bruder, and was privately held until it was purchased by Sherwin-Williams in 2007. [1] M.A.B. Paints was well known throughout the Philadelphia metropolitan area because of their Make America Beautiful campaign and their sponsorship of local professional and amateur sports teams and charities, including the 2007 United States Club Lacrosse Association ...
In the July 1904 edition of its monthly publication, paint manufacturer, Sherwin-Williams, reported the dangers of paint containing lead, noting that a French expert had deemed lead paint "poisonous in a large degree, both for the workmen and for the inhabitants of a house painted with lead colors."

The second most important part of FBE coatings is the curing agent or hardener. Curing agents react either with the epoxy ring or with the hydroxyl groups, along the epoxy molecular chain. Various types of curing agents, used in FBE manufacture, include dicyandiamide, aromatic amines, aliphatic diamines and organic acid anhydrides. [6]
The Sherwin-Williams Company is an American paints and coatings company based in Cleveland, Ohio. It is primarily engaged in the manufacture, distribution, and sale of paints, coatings, floorcoverings, and related products with operations in over 120 countries. [ 2 ]

Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.
The epoxy value is defined as the number of moles of epoxy group per 100g resin. So as an example using an epoxy resin with molar mass of 382 and that has 2 moles of epoxy groups per mole of resin, the EEW = 382/2 = 191, and the epoxy value is calculated as follows: 100/191 = 0.53 (i.e. the epoxy value of the resin is 0.53). [6]
FR-4 epoxy resin systems typically employ bromine, a halogen, to facilitate flame-resistant properties in FR-4 glass epoxy laminates. Some applications where thermal destruction of the material is a desirable trait [ citation needed ] will still use G-10 non flame resistant .
